1959 Wolseley 15/50 Tires

The 1959 Wolseley 15/50 uses two primary tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both sizes are tied to a 15-inch rim, so the main distinction is not wheel diameter but tire format and construction style.

That means the real choice is whether the car should keep a traditional bias-ply look or move to a radial-format tire. Before selecting either size, confirm the actual wheels on the car, especially if they may have been changed over the years, and make sure the intended tire matches the wheel width and the car's clearance needs.

Both primary tire sizes used on the 1959 Wolseley 15/50 are built around a 15-inch rim diameter. That applies to the 560-15 bias-ply fitment and the 155R15 radial fitment, so wheel diameter stays consistent even though the tire construction can differ.

Rim diameter alone does not settle the whole fitment question, because wheel width still matters when comparing available tires. A car that still has its original-style wheels may accept one size path differently than a car with later replacements, so it is worth measuring the wheels before choosing between the bias-ply and radial formats.

Yes. The 1959 Wolseley 15/50 Base uses the same two primary fitment paths as the model core: 560-15 in bias-ply construction and 155R15 in radial construction. Both are 15-inch tire sizes, so the question is mainly one of construction and presentation.

That makes the Base model fairly straightforward to shop for, but the car's present setup still needs to be checked. A restored car aimed at earlier visual authenticity may lean toward 560-15, while a driver-focused car may be set up around 155R15, and either choice should be matched to the wheel width actually on the vehicle.

On the 1959 Wolseley 15/50, 560-15 is the bias-ply tire size. It uses the older numeric sizing format common to the period, and the available products in this size are bias-ply tires rather than standard radials.

That matters because a 560-15 bias-ply tire gives the car a more traditional visual character and opens up blackwall, narrow whitewall, and wide whitewall choices. If the goal is to move away from bias-ply construction, the radial path should be evaluated separately through the available radial equivalents and checked against wheel width and vehicle clearance.

Two radial equivalents are available for 560-15. The first is 155R15, which is the 80-series metric radial equivalent, and the second is 560R15, which is the bias-look radial equivalent intended to preserve a more traditional visual style while using radial construction.

These alternatives keep the 15-inch rim diameter but use different sizing conventions and may suit different goals. A recommended rim-width range of 4 to 5 inches applies to the equivalent path, so the wheel width should be confirmed before conversion, along with basic clearance around the fenders, steering, and suspension.

That depends on how the 1959 Wolseley 15/50 is being used and how closely the owner wants to retain an earlier period-style presentation. The primary choices are the 560-15 bias-ply size and the 155R15 radial size, with 560R15 also available as a bias-look radial equivalent.

Bias-ply construction generally makes the strongest visual match for a traditional restoration theme, especially when whitewall styling matters. Radial-format choices can be considered when the car is driven more regularly, but the switch should be approached as a fitment decision rather than an automatic substitution, with wheel width and clearance checked first.

Start by confirming that the car is staying with the 560-15 bias-ply size rather than the 155R15 radial path. From there, the main selection factors are sidewall appearance, brand, tire series, and wheel compatibility, since 560-15 is offered in blackwall, narrow whitewall, and wide whitewall form.

The best choice depends on whether the Wolseley is being restored for a traditional look or prepared for more regular display and road use. It also helps to compare rim-width specifications and load figures where they are stated, since not every 560-15 option is built around the same wheel-width range or product character.

The 1959 Wolseley 15/50 offers meaningful sidewall variation, especially in the 560-15 bias-ply size. Blackwall, narrow whitewall, and wide whitewall options are available there, while the 155R15 radial choices are presented as blackwall tires.

That gives owners a clear appearance decision before getting deep into brand and series details. A blackwall tire keeps the look restrained, while narrow and wide whitewalls create a more decorative period-style presentation, so the sidewall should be chosen to match the restoration direction and the visual character already established on the car.

Tires for the 1959 Wolseley 15/50 are available from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. Those brands cover both size paths, with the 155R15 options concentrated in radial series and the 560-15 options spread across classic bias-ply and specialty offerings.

Brand choice should be treated as one part of a broader fitment decision rather than the whole answer. The more useful comparison is how each brand's offering aligns with the intended tire size, construction, sidewall style, and wheel-width needs, because that combination affects both the look of the Wolseley and the practical fit on the car.

For a period-style 1959 Wolseley 15/50, the 560-15 bias-ply size is usually the strongest starting point because it preserves the vintage numeric format and opens up traditional sidewall treatments. Blackwall, narrow whitewall, and wide whitewall choices make it easier to match the car's restoration theme.

The right version depends on how formal or understated the finished car should appear. Owners pursuing exact historical authenticity should compare the tire choice against marque references, period photos, or restoration records, since the correct size alone does not prove a particular whitewall treatment or brand was used on a specific car.

Tire construction changes the visual character of a restored 1959 Wolseley 15/50 more than many owners expect. A 560-15 bias-ply tire gives the car a more traditional period presentation, while a 155R15 radial introduces a later-style sizing format and a different visual impression even though the rim diameter remains 15 inches.

That difference becomes more noticeable when sidewall treatment is part of the restoration plan. Whitewall bias-ply tires can reinforce an earlier visual theme, while blackwall radials tend to look cleaner and more restrained, so the construction choice should support the car's overall restoration direction rather than be treated as a purely technical decision.

Yes. Modifications can change tire fitment on a 1959 Wolseley 15/50 even when the nominal tire size remains 560-15 or 155R15. Aftermarket wheels, wheel-width changes, altered offset, suspension work, or body and fender modifications can all affect how much space the tire has once it is mounted.

A car that no longer sits on original-style wheels should be checked carefully before any purchase is finalized. Measuring wheel width, confirming the 15-inch diameter, and looking at steering and fender clearance during full movement are all worthwhile steps, especially when converting between bias-ply and radial construction or evaluating a radial equivalent.

Before driving a 1959 Wolseley 15/50 on new tires, inspect the wheels, valve stems, and overall mounting condition, then make sure the tires are inflated appropriately for the tire and vehicle setup. It is also wise to look over the suspension and steering components so the new tires are not being asked to compensate for worn hardware.

A short initial road test can reveal rubbing, pull, vibration, or clearance issues that are easier to address early. Collector cars that spend long periods parked deserve extra attention, because an otherwise attractive Wolseley may still have stale wheel hardware, alignment issues, or old chassis parts that affect how the new tires behave.

Collector-car tires on a 1959 Wolseley 15/50 should be checked regularly for pressure, tread condition, sidewall cracking, cuts, bulges, and any sign of air loss. That applies whether the car is on 560-15 bias-ply tires or 155R15 radials, because low annual mileage does not prevent age-related deterioration.

Storage conditions matter nearly as much as miles driven. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and periodic inspections remain important even when the Wolseley is used sparingly, since collector vehicles can sit long enough for condition changes to go unnoticed.
